Ingredients:
Dough:
300 g of flour (about 2.5 cups)
1/2 tsp salt
1/2 tsp baking soda
1 tbsp vinegar
6-8 tbsp sour cream (thicker, tangier Eastern European-style sour cream)
Filling:
1 kg of potatoes (about 2.2 lbs)
60 g of butter (about 4.2 tbsp)
Salt and pepper
4-5 large cloves of garlic
Dough:
Combine the flour, salt, baking soda, vinegar, and sour cream in a bowl. Mix until the dough is slightly softer than the dough used for dumplings.
Filling:
Peel the potatoes and boil them in salted water. Drain the water and mash the potatoes while they are still hot. Add the butter, a generous amount of pepper, and the garlic (pressed through a garlic press). Mix everything well and let it cool.
Roll out the dough to a thickness of about 3 mm (1/8 inch). Cut out circles for the pastries and shape them into pies. Place the pastries on a greased baking sheet or parchment paper. Brush them with oil, sprinkle them with pepper, and bake them for 25 minutes at 180°C (about 350°F).
